工具機機上量測技術

On-Machine Measurement Technology for Machine Tools

摘要


工具機會因為多項原因產生誤差,而機上量測功能因操作複雜或設備昂貴無法廣泛的應用在加工廠中,導致無法即時修正誤差改善精度。本文首先介紹工具機43項誤差,接著探討國外商用控制器針對誤差所提供的補償功能及儀器量測方式,最後提出工研院的解決方案,透過設計教導式人機介面,簡化使用者操作儀器的困難度,並撰寫Marco程式將各項量測步驟與方式自動化,精簡誤差量測過程與簡化操作難度,在設計圖像化介面對應實際機台位置,快速理解需填入的參數位置,完成機上量測功能,提高廠商使用意願,改善機台精度。

There are many reasons for the error of the machine tool, and the on-machine measurement cannot be widely used in the processing plant due to the complicated operation or expensive equipment, which makes it impossible to correct the error immediately and improve the accuracy. This article first introduces the 43 errors of machine tools, then discusses the compensation functions and instrument measurement methods provided by foreign commercial controllers for errors, and finally proposes the solution of ITRI, through the design of a teaching man-machine interface, which simplifies the difficulty of operating the instrument for users, and writes a Marco program to automate various measurement steps and methods. In the design of the graphical interface corresponding to the actual machine position, it quickly understands the parameter position that needs to be filled in, completes the on-machine measurement function, increases the willingness of the manufacturer to use, and improves the accuracy of the machine.
